15. Deer

Deer are not known for being aggressive, but they do kill around 240 people per year (and probably more than that). Most of these deaths are from car accidents, since deer have a funny little habit of suddenly jumping out onto the road, despite a car speeding down it.

Of course, we’ve confused them by putting death lanes smack in the middle of their territory. They haven’t exactly had a lot of time to evolve and adapt to the changing environment. Hopefully, deer will learn how to cross the street and stop causing so many accidents, because they’re victims of them too.
